description With the development of clonal production systems in forestry, there is a need for efficient indicators to determine the production capacity of the system. The Clonal Propagation Productivity Index (CPI) is recommended to determine the effect of possible technical improvement on the production capacity. CPI allows assessing productivity differences according to the month of year, between years, between species, between nutrition programs, irrigation programs, or other changes in the clonal production system. It is based on several efficiency criteria for each of the universal components in a clonal production system: a) Mother stock garden, b) Rooting area, c) Acclimatization area. In mother stock garden were considered as parameters 1) planting density; 2) mortality; 3) harvest frequency; 4) shoot production rate per mother plant. Meanwhile, for the rooting area the parameters were, 1) first quality control (previous cutting preparation); 2) rooting rate; 3) rooting duration. In the acclimatization area, survival rate and final quality control were included. Finally, a unit of time in weeks is required to produce an effective cutting. The CPI value for teak (Tectona grandis L.) was 130 and for melina (Gmelina arborea Roxb.) 279 effective cuttings/m2/month. The minimum value that the index has registered was for Dipteryx oleifera with 18 cuttings per month per m2, while the maximum value can reach 330 cuttings in the index with an optimal Gmelina arborea production system. It is concluded that CPI is an easy and accurate indicator to estimate production capacity in a clonal system, sensitive enough to determine the effect of any improvement in the technological package. The proposed index includes all the factors affecting mass clonal production in forestry systems.

Se propone el Índice de Propagación Clonal (IPC) para determinar el efecto de cualquier mejora técnica sobre la capacidad de producción. El IPC permite evaluar diferencias de productividad según mes del año, entre años, entre especies, entre programas de nutrición, programas de riego o cualquier otro cambio en el sistema de producción clonal. Se basa en una serie de criterios de eficiencia para cada uno de los componentes universales en un sistema de producción clonal: a) Minijardín clonal, b) Área de enraizamiento, c) Área de aclimatación. En el minijardín clonal se consideraron como parámetros 1) la densidad de siembra; 2) la mortalidad; 3) la frecuencia de cosecha; 4) la tasa de producción de brotes por planta madre. Mientras que en el área de enraizamiento los parámetros fueron, 1) primer control de calidad (preparación previa del esqueje); 2) tasa de enraizamiento; 3) tiempo de enraizamiento. En el área de aclimatación se incluyó la tasa de supervivencia y el control de calidad final. Finalmente, se requiere una unidad de tiempo en semanas para todo el ciclo de producción clonal. El valor del IPC para la teca (Tectona grandis L.) fue de 130 y para la melina (Gmelina arborea Roxb.) de 279 estacas efectivas/m2/mes. El valor mínimo que el índice puede alcanzar es el registrado para Dipteryx oleifera con 18 estaquillas/m2/mes. Mientras que el valor máximo podría alcanzar las 330 estaquillas/m2/mes en un sistema de producción clonal óptimo con la especie Gmelina arborea. Se concluye que el IPC es un indicador fácil y preciso para estimar la capacidad de producción en un sistema clonal, lo suficientemente sensible como para determinar el efecto de cualquier mejora en el paquete tecnológico. El índice propuesto comprende todos los factores que afectan la productividad de estaquillas a escala masiva comercial en sistemas forestales.
